Maybe "I will eat later"?
Maybe "Later I will eat?
I got wrong because I said Later I will eat.
Yes, I think we would use the future tense here.
"I will eat later" = also accepted as a correct answer.
I think this is the only exercise so far where the adverb is at the beginning of the sentence. When is that permitted and when is it mandatory?
I don't know for certain, but I think adverbs of time can be placed pretty much anywhere in the sentence.
Nanti saya makan.
Saya nanti makan.
Saya makan nanti.
are the same?
Don't take my word as 100% fact, but I think there'd be differences in emphasis, but pretty much the same yeah
Could i say "saya akan nanti makan"?
That doesn't sound right to me. Possibly "Nanti saya akan makan" but I think overwhelmingly, if the timing is clear you would avoid temporal markers like 'akan',
I eat later can be grammatical, but it needs context, unlike "I will eat later"
